In the majority of adult men, the [[foreskin]] normally retracts to reveal the head of the penis. In newborns, it is common for the foreskin to be fused to the head of the penis by the [[synechia]], thus rendering it non-retractable. The foreskin usually separates from the glans and becomes retractable with increasing age.

Almost all boys are born with the foreskin fused with the underlying glans penis. Most also have a narrow foreskin that cannot retract. Non-retractile foreskin is normal at birth and remains common until after puberty (age 18). Some boys develop retractile foreskin earlier, and about 2 percent of males have a non-retractile foreskin throughout life. Non-retractile foreskin is not a disease and does not require treatment.
